We report on the optical spectroscopic observations of host galaxy hyperactive repeating fast radio burst, FRB 20240114A. The is a dwarf at redshift $z=0.1306\pm0.0002$. With rest-frame coverage 4300-7900 \AA, we have detected H$\rm{\alpha}$, H$\rm{\beta}$, [O III]$\lambda\lambda$4959,5007, [N II]$\lambda\lambda$6548,6583, and [S II]$\lambda$6716 emission lines. line ratios suggest that ionization in dominated by star formation. formation rate (SFR) derived from H$\rm{\alpha}$ $(0.06 \pm...
In today's university era, reforming the English teaching model has become a major research topic for researchers. Based on this, this paper adopts hierarchical and progressive construction method to further explore reform of in context educational ecology. First, discusses development layered approach various countries current status approach. By allowing use approach, data related were analyzed organized. The combination internal optimization, data-theoretic learning algorithms, federation...
In this paper, the spatial-alternated Julia sets are discussed, which obtained by alternated iteration of quadratic family zm+1,n+azm,n+1=(1+a)2zmn2+ci,i=1,2. The control is accomplished using feedback control. Then linear generalized synchronization two different discussed. simulations demonstrate effectiveness methods.
Paths will be re-planed timely according the change of obstacles and target position for Human Following Robots (HFRs) so that they can run safely rapidly. Traditional path planning algorithms are generally focused on how to avoid or connect with new effectively, however there rarely studies elimination robot heading fluctuation which is caused by re-planning. Concerning this issue, we introduce a novel dynamic re-planning algorithm AT* based A* walkable area thinning. When robots difference...
This paper presents a new weak signal detection method with Duffing oscillators. The state transition from chaos to periodic orbit is monitored by the Melnikov function. When oscillator in state, function remains zero. Otherwise, will oscillate around As result, clarified. With aid of function, frequency identified through intermittent phenomenon an array oscillator. amplitude and phase are also plot array. To get parameters, steepest descend algorithm used. Simulation results show...
In this article, the fractal behavior in generalized alternated system is discussed. Take classical set as an example, anti-synchronization of Julia between two different systems discussed using adaptive control method article. The also accomplished by synchronizing their iterative tracks. simulations illustrate effectiveness and correctness method.
In this paper, the fractal behaviors in 2-D Logistic map are discussed. First, definition and some properties of set given. Moreover, several synchronous definitions between different maps introduced such as complete synchronization, coupled adaptive synchronization. The synchronization is accomplished by synchronizing their iterative tracks. simulations illustrate effectiveness correctness these methods.
We present PP-Menus, a novel technique for enhancing the performance of pen-based interfaces. PP-Menus are pressure-based pie menus, which implemented by using pen input pressure values to localize traditional menus. possess two states, i.e. stationary state and tracking state. A variation can switch between states. quantitative experiment shows that significantly outperformed menus on task speed, there was no significant difference types accuracy.

To solve the problem of low accuracy traditional financial crisis early warning model, this study proposes a model based on random forest algorithm. First, according to formation mechanism crisis, from aspects operation ability, development profitability, solvency, cash flow, ratio structure and so on, paper selects detection indicators crisis. Then, algorithm is used screen calculate weight indicators. Through comparison results thresholds, warnings are realized. The experimental show that...
This paper presents ongoing research conducted through collaboration between the University of Arkansas at Little Rock and Department Education to develop an entity resolution identity management system. The process includes a multi-phase approach consisting data-quality analysis, selection entity-identity attributes for resolution, defined rule set using open source entity-resolution system named OYSTER used entropy identify potential false positive negative. is first known its kind...
We solve the fully-connected Ising model in presence of dissipation and time-periodic field, with corresponding Lindblad equation having a Liouvillian. The dynamics magnetizations is studied by using both semiclassical approach numerical simulation help permutation symmetry. shows transition from periodic response for small field amplitude to chaotic large amplitude. trajectory Lyapunov exponents are calculated, which support existence phase. But exact simulation, scaling analysis Floquet...
